Abstract: A can for spraying atomized liquids comprising a pair of coaxial cylinders, the outer cylinder forming the sealed can body. The liquid to be atomized and sprayed is contained within the central cylinder above a piston. The central and outer cylinders are in fluid communication through openings in the central cylinder near the bottom of the can. The piston, which is double-ended, is movable located within the central cylinder. A gas or other fluid under pressure is located in the volume between the central and outer cylinders, thus exerting a force on the bottom of the piston to drive the fluid to be sprayed out of the central cylinder when the atomizing valve is manually actuated.
